I like the idea.

Reminds me of how in OS X, the Finder can be extended to support more file formats by a plugin stored in an application bundle. The Finder knows how to show previews for several document types (audio, video, multi-page document). It recognizes a limited set of formats (like jpg, mov, pdf), and the app's plugin simply needs to convert its own format into one of these formats. 

That's a lot simpler than having to write an actual viewer plugin (which also would have to be maintained for every new version of the viewer). E.g., Etoys stores a thumbnail in its project file which are simply zipped, so the preview plugin just extracts the thumbnail picture from the project. Tt does not have to care about the actual UI used to display the thumbnail.
